The rear liftgate struts in some Mazda CX-5 models can occasionally fail due to a combination of factors that can include poor material quality, wear and tear over time, and external environmental factors. Here's a detailed explanation of why this issue occurs and the steps you can take to fix it:
Why Do Rear Liftgate Struts Fail?
Material Quality: In some instances, the materials used in manufacturing the struts are of suboptimal quality, leading to premature wear or failure. This may be due to cost-cutting measures or defective parts from suppliers.
Wear and Tear: Liftgate struts are constantly exposed to cycles of compression and expansion. Over time, the gas inside the struts may leak or lose pressure, reducing their ability to support the liftgate's weight.
Environmental Factors: Exposure to extreme temperatures and weather conditions can adversely affect the performance of liftgate struts. Cold weather can cause the gas inside the struts to contract, while heat can accelerate the degradation of seals and components.
Symptoms of Failing Liftgate Struts
Difficulty in Opening or Closing: A clear sign of failing struts is the struggle to open or close the liftgate as easily as before.
Liftgate Falls Without Notice: When the struts are failing, the liftgate may start to sag or even drift downward unexpectedly, posing a safety hazard.
Noisy Operation: Hearing creaks, pops, or other unusual noises when using the liftgate could be an indication of deteriorating struts.
How Can This Issue Be Fixed?
Inspection and Diagnosis: Initially, inspect the struts for any visible damage or leaks. Check if the liftgate remains open on its own or slowly droops down.
Replacement of Struts: The most effective solution is to replace the failing struts with new ones. It's advisable to purchase high-quality, OEM (Original Equipment Manufacturer) struts or reputable aftermarket options designed for your specific model.
Cleaning and Maintenance: Regularly clean the strut shafts to remove debris, salt, or corrosion that could impair their function. Apply protective sprays if necessary to enhance their longevity.
Installation: Installing new struts is generally a straightforward DIY task if you're familiar with basic automotive repairs. If not, a professional mechanic can perform this replacement quickly and safely.
Regular Inspection: Periodically inspect the liftgate and its components to ensure they are in good working condition and address any issues immediately to prevent further complications.
By understanding these factors and following the recommended steps, you can effectively address and fix issues with the rear liftgate struts of your Mazda CX-5.
